Our Take

from the Cars.com expert editorial team

From the 2017 Los Angeles Auto Show, Mark Williams takes a look at the rugged 2018 GMC Sierra 2500HD All Mountain Concept.

What it is: The Sierra 1500 is GMC's entrant in the half-ton, full-size pickup truck segment. It’s a corporate cousin of the Chevrolet Silverado 1500, sharing the same platform, engines, body styles and major mechanical features. The Sierra has different styling, particularly in front, and GMC positions its vehicles as more upscale than Chevrolet’s. Competitors include the Ford F-150, Ram 1500 and Toyota Tundra.

Three cab styles — regular, extended and crew — and three engines are available for the Sierra 1500. All the engines are gas-powered: a 4.3-liter V-6, and 5.3-liter and 6.2-liter V-8s. As with the Silverado, the Sierra is available in 2500HD and 3500HD heavy-duty versions that offer a turbo-diesel engine and higher payloads and towing capacities.

New for 2018

The base truck gains a standard 7-inch touchscreen radio and a backup camera. The tire pressure monitor now includes a tire-fill alert that monitors how much air is pumped into a tire.

Sierra 2500HD and 3500HD
The GMC Sierra 2500HD and 3500HD heavy-duty pickup trucks are the true workhorses of the Sierra lineup and are designed for hauling heavy payloads and towing large trailers.

Changes for 2018 include a standard backup camera on all models with a cargo bed, a standard 7-inch touchscreen radio for the base model and a new grille for the Denali version.

What's Special

  • Standard 360-horsepower, 6.0-liter V-8
  • Available 445-hp, turbo-diesel 6.6-liter V-8 with 910 pounds-feet ...

Truck is great but needs some updates such as push button start/stop and door sensors for locking/unlocking the truck. Overall, great truck with great towing capabilities. Read full review

Warranty FAQs

What is a Bumper-to-Bumper warranty?

Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.

What is a Powertrain warranty?

Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

What is included in Roadside Assistance?

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

What other services could be included in a warranty?

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.

What does CPO mean?

A certified pre-owned or CPO car has been inspected to meet minimum quality standards and typically includes some type of warranty. While dealers and third parties certify cars, the gold standard is an automaker-certified vehicle that provides a factory-backed warranty, often extending the original coverage. Vehicles must be in excellent condition and have low miles and wear to be certified, which is why off-lease vehicles feed many CPO programs.
